You can obtain `<PRIOR_RANCHER_VERSION>` and `<RANCHER_CONTAINER_NAME>` by logging into your Rancher Server by remote connection and entering the command to view the containers that are running: `docker ps`. You can also view containers that are stopped using a different command: `docker ps -a`. Use these commands for help anytime during while creating backups.
